vIIVIPROVEM ENT IN CARIRiDGE-REIRA-CTORS FOR MANY-CHMBEREDIlRE-ARMS.

Specification forming part of Letters Patent No. ll, dated January 17, 1865.

To allJ whom it may concern:

Be it known that I, WILLIAM C. DODGE, ot' liVashington city, in the District of Columbia, have invented certain new and useful Improvements in Fire-Arms; and I do hereby declare that the following isafull and exact description thereof, reference being had to the accompanying-drawings, making part of this specification, and to the letters of reference vmarked thereon, which 'several figures will be 'hereinafter explained.

Similar letters indicate corresponding parts in each of thev figures.

My invention relates to that class of rearms denominated many-chambered,7 and in which metallic cartridges are now generally used.

It consists primarily in the simultaneous and rapid removal therefrom of the cartridge cases or shells, and in certain devices adapted to produce that result. e

In such arms asv usually constructed the cartridge-cases are removed singly, or one at a time, and in most cases by means of a rod or bolt separate or detached from the arm. In

the great majority of revolving arms the cylinder has also to beremoved or detached from the stock or frame to permit the removal of the cartridge-cases and the reloading of the arm. It is to remedy all these difficulties or objections that my invention is intended.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The principal device used in my invention is-the retractor, which removes the cartridgecases. This retraetor consists of a metallic plate of any suitable form to adapt it to the arm to which itis to be applied,and which is so constructed as to lit snugly against or within that end of the barrels or cylinder in which the cartridges are inserted. It may be as imple disk, as shown at a, Figure I, in which case it will be provided with perforations correspending in number, size, and location with the chambers of the arm; or it may be in the vform of a spider or smaller disk, with por tions of its periphery cut away to correspond with the chambers, as clearly shownin Fig. 5. In the former case it will fit snugly against the Hat end of cylinder B when in place. In

face of al to come flush with the surface of the y end of the cylinder or barrels, asshown in Figs. 2 and 3. This plate a is provided with a centralstein passing into or through a hole bored longitudinally in the center of the cylinder or barrels. This stem b is clearly shown in Figs. 2 and 3, and its ofiice is to support the plate a' and guide it in its operations. On this Stem b is usually mounted a spiral spring, c, for the purpose of automatically returning the plate at to its position when it has been pushed or drawn outward for the removal of the cartridge-cases.

Fig. 2, which is a longitudinal vertical section. of a portieri of the barrel and frame of a. revolver with its cylinder B attached, shows the retractor a, with its stein b and spring c applied, with the end of the stein protruding from the front of the cylinder. This method of appl ying it enables the retractor a to be operated by pressing against thev end of the stem b o'r the nut d thereon, as clearly shown. This represents my invention applied to a cylinder which is loaded in the usual manner at its rear end.

out of the way of theretractor a, as clearly In this case the cylinder B is secured in any suitable manner to the recoil-plate E or rear portion of the frame. The stem b may be made to protrude :as in Fig. 2, but at the rear, instead of the front end of the cylinder; or it may be incased within the cylinder, as shown in Fig. 3, which will be hereinafter explained.

Where my invention is to be applied to revolvers whose cylinders are loaded at the rear the frame C, with the barrelAand cylinder B attached thereto, is to be so pivoted or hinged that it can be swung round or moved so as to bring the rear end of the cylinder clear of the recoiLpla-te E or other portion of the frame or stock.E This, however, is only necessary in those cases where it is desired to operate the nut d on the end of the stem b.

Fig. 3 represents a side elevation of afourharreled firearm with the front broken away for the purpose of exhibiting the method ot' applying my invention jto manychambered arms whose barrels do not revolve.

A represents the body of the arm, of which y o are the barrels, usually bored in a single solid piece of metal. In the center, between the barrels,-is bored a hole, lr, which extends a proper distance to admit the introduction of the stem b, with its spring c, in case the latter is deemed necessary. A hollow nut, y, havinga screwthread cut on its periphery, is tirst slipped on the stem b. Then the spring c is placed on the stem and secured thereon by means ot' the This nut d is made of such a size as to tit accurately and yet move readily within the hole k. The hole in the nut y is also made to correspond in size with the stem b. By these means the stem b and plate ct are accurately guided in their movements. vAfter the nut y, spring c, and nut d have been placed upon the stem b the nut y is screwed into its seat at the mouth of hole k, whereby the retractor, with its stem and spring, is secured in its proper position and prevented from becoming detached. The opposite edges z z of theretractor-plate a are slightly roughened, and, if desired, may be allowed to project slightly beyond the sides ot' the barrels, as shown in Fig. 4, for the purpose of more securely and readily grasping it hetween the thumb and linger for operating it.

-In all cases the stem b may be provided' Ywith a feathenand yits seat with a corresponding groove, which will so guide the retractorplate a in its return, after having been shoved or drawn out, as to cause its perforations or recesses to exactly coincide with the chambers of the arm; or any other mechanical device may be used, it' desired, for the same purposeas, for instance, one or more pins or studs may be secured to the under or inner surface of a and made to workin corresponding holes in 'the cylinder or barrels, or in grooves in the sides thereof.

It is also obvious that instead of the central stem, b, two or more stems may be attached to the plate a., near its outer edges, and made to work in corresponding grooves or holes in or near the periphery ot' the cylinder or barrels.l

It is also further obvious that the plate a may be made in two or more parts, and so applied as to remove but(a portion of, the cartridge-cases at a time; but that would be but a modification ot' my invention, and one which I do not deem desirable, as it'would increase the number of parts and consequently the cost of construction, and at the same time lessen the ease and rapidity of its'operatiom its weight, bulk, or expense.

In case the disk a, as shown in Fig. 1, is used, its periphery may be milled or otherwise roughcned, or proper recesses may be cut in the sides of the cylinder or barrels, at the end where the plate a is applied,- for convenience in grasping it when it is desiredto operate it by drawing instead of pushing it out.

The operation is very simple, s0 much so as scarcely to require fur-ther explanation. After the arm has been discharged the cylinder or barrels is so moved in relation to the other parts ot the arm as to expose its end containing the cartridge-cases, when, by either pushing or drawing the rctractor-plate a outward, all the cases, whatever their number, are simultaneously and instantly ejected from the arm. By this means the arm is instantly prepared for reloading with the least possible loss of time, without detaching any ot' its parts from the frame or stock, and without the use ot' any separate rod, bolt, or other -part for that purpose.

The advantages to be derived from this improvement in tire-arms are manifold. In the first place, as revolving arms are now constructed, the soldier or person using them is unable'to discharge them more times than they contain loads, for the reason that the process of removing the cartridge-cases is so slow and tedious, and for the further reason that the cylinder has generally to be detached entirely from the arm, and some separate device used for the removal of the cartridge-cases. So great 'is the diiiculty ot1 performing this operation in the case of mounted men, who more than all others use revolving arms, and so imminent is the danger of loosing or dropping some of the detached parts, that usually in battle no effort is ever made to reload the arm after it has been once emptied of its charges; and in case the arm is to be used in the dark, as often happens both with soldiers and civilians, the difficulties here mentioned are greatly increased, whereby valuable lives are oftentimes lost and the efficiency of the arm greatly lessened.` By my invention all these difficulties are at once removed,the et'- iiciency and value of the arm largelyincreased, and that, too, without adding perceptibly to The invention is simple, readily applied, not easily injured or disarranged, and not interfering in the least with they compactness or beauty of the arm.

Ido not intend to limit myself to the mechanical details or devices herein described,

as it is obvious that they may be greatly varied or others substituted without departing from the spirit of my invention; but,

Having thus described my invention and various methods of applying and utilizing the same, what I claim as my invention, and desire to secure by Letters Patent of the United States, is

1. The ejection simultaneously of two or more cartridge-cases from a many-chambered 45,912 u i l g fire-ann in the manner and by t'he means which is made to extend throughthe. cylinder substantially as herein set forth, whether the or barrels and project: at. either lthe front; or
